TO ALL WHOM 1T MAY OONCERN:

Be it known that I, LEMUEL P. JENKS, ofthe city ot' Boston, county of Suffolk, and State ot' Massachusetts', have invented a new and improved ldaehine for the Purpose of Measuring Water and other Liquids, and for 4a Motor; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters ci' reference marked thereon. VAnd in the drawings annexed- Figure 1, plate 1, is a View of the end or" my machine.

Figure 2, plate 1, is a side view.

Figure 3, plate 2, is a vertical section through the centre of lig. 2, plate 1.

Figure 4, plate 2, is a horizontal section of partof iig. 3, at the lines B B, hereinafter more particularly explained.

Eigure 5, plate 2, is a view of a cylinder-head, (seen froml the inner side and Figure 6, plate 2, is a section of iig. 5, at the line A. p i

In the drawings annexed, O C C, figs, 2 and 3, show (from the side) a cylinder, lying horizontally, and supported by a bottom or standard attached to it, being cast in the same piece. D, fig. 1, and D D, figs. 2 and 3, represent, respectively, one or two cylinder-heads, vwhich swell out in a hemispherical projection from the direction of the centre of the cylinder O C C. These cylinder-heads are firmly fastenedv by the screws DX DX D D DX, figs. 1 and 2, to the respective Vends of the cylinder C O O, and bear, projecting from the inner surface, (into the cylinder O C 0,) a frame called the hammer-frame, consisting of two upright slabs or bars ot' metal, EE, figs. 5 and 6, connected bya horizontal slab of metal, E EX, fig. 3, and EKA-ig. 6, called the upper spring slab, also projecting from and firmly joined to the inner side of thc cylinder-heads. These upright slabs E E bear in the inner sides, opposite to cach other respectively, a perpendicular groove, seen in fig. 6, plate 2. These grooves bear what is called the hammer, E F, igs. 3 and 6, and F F F, fig. 5, which is a slab of metal, sliding up and down in the aforesaid grooves, and being a solid slab at the bottom, (as seen in iig. 5,) with an inclined planeA thereat, (see fig. 3,) and resolving'itself above into two arms of a fork, and seen in figs. 5 and 6. At the top of these arms, (and, consequently, at the top of the hammer,) i`s fixed, loosely rotating, a roller, Gr G, fig. 3, and G, iig. 5. From just below the middle of the hammers, projects horizontally toward the respective cylinder-heads which -bear them, a shelf, H H, seen in iig. 3, bearing each, on its upper side, a perpendicular knob or conical pr jeetion, J J, iig. 3. These knobs, called the .lower spring knobs, pass up through the centre each of a spiral spring, Il, Il, seen in section in g. 3, plate 2, which. springs these knobs hold in place.

From the lower side of the upper spring slab, E EX, g. projects downwards a knob, K K, lig. 3, called the upper spring knob, which assists inholding in place the spring which surrounds it. L L, iig. 3, are two latches or pawls, playing loosely on a bearing or shaft, (seen in fig. 3,) which shafts are supported by the hammer-frame E E, iig. 5. M M, iig. 3, (M, 5g. 5, and M, iig. 6,) are two bars, called the latch spring bars. rldhese are a portion of the hammer-frames, and have each a cavity on the inner side, (see figs. 3 and 6,) by which is retained in place a small India-rubber (or other) spring, N N, fig. 3, and N, iig. 6, called the latch spring, the other end of which tits into a hollow or cavity in the upper partof the latches L L, (see figs. 3 and 6.) By means ot' these vlatch springs the upper parts or ends of the latches L are pressed into a notch in the outer side of the hammers F F, (see iig. 3,) and thus the hammers (notwithstanding the tendency of the springs ll, Il, to drive them down) are held in place. O O, iig. 3, is aseetional view et' the piston, which plays back and forward in the cylinder C C. There intervenes, however, between the piston and the cylinder O O, anothcrvcylinder, C CX' CX, fig. 3, supposed to be of Babbitt metal, or other metal not readily oxidizable by water, and cast in a molten state, into the cylinder O C. The use of this ,Babbitt metal cheapens the cost of boring the cylinder, and prevents the rusting which would occur if the bare iron cylinder O C were solely used. The piston O O is surrounded at its edges by a cylinderl firmly attached to it, O* Oi Oz O, iig. 3, cast in the same piece, which is called the piston cylinder, and is cutaway at its lower part, at its ends, at Oz Oz, tig. 3, sufficiently to allow the passage oi' the piston cylinder to its extreme point ot' play without interfering with the passage ofthe hammers F F up and down. The Babbitt cylinder OX, Sie., and the main cylinder O, are also cut away at this me o point to allow the hammers to play up and down. From cach side of the pisticn O, and above the axis of 'the cylinder C C, (sce fig. 3,) and cast upon the piston, is a piece of metal, O O", projecting horizontally half its length, and then bending upward atan'anglc of aboutfortyvc degrees, (thus having each, an inclined plane on its upper surface,) called the hammer horn," The width o' these hammer horns is just sufiioient to permit their passa-ge through the forked arms, (see'lig. 5,) of the hammers.' Oq OQ", iig. 3,are two shelves, knobs, or projectons, on each side of the lower part of the piston, and are called the "latch knobs. In the top of the piston cylinder O", 82e., is a slot7 (sec lig. 3,) at I P, which slot does not pass entirely through the piston cylinder, and is sufficiently wide to admit the passage. back and forward of thepn Q, 3, called the clock pin, This clock pin has upon it a circular disk or button, QX QX, lig. 8, which button plays in a slot formed in the projection R It, seen in section in iig. 3, and thus keeps the clock pin Q in place. Below the main cylinder, and with its centre in the same perpendicular line, (see fig. 1v, plate 1,) is u tubulaiaapertnre oreylind1icalhole,cast in the mass of metal ot' which the main cylinder forms a part, called the valve tube. This valve tube is lined with Babbitt or other metal not easily oxidizable, supposedV to be enst in it, and making the two cylinders TT, TT, seen in section in ig. 3, and T T, dto., fig; 4'; This valve tube has running across its centre a block el' metal, S S, figs. i3 and 4, forming a diaphragm, which divides the righthand portion of thc valve tube from the left-hand portion. This portion S S is lixed firmly in its position, and has running through its centre, coinoident with the axis of the valve tube, a 4small cylindrical aperture, through which runs back and forward a rod or shaft, U, figs. 3 and 4, called the valve shaft, which has attached to it, at each cnil, a buttomV VX, x'igs. 3 and 4, callodthe valve buttons.` To the sides of the respectivo buttons V VX, which are nearest the block S S, is respectively, joined by its end, a short cylinder, W W W WX, fig. '3,' and W, dto., g. 4.-, called the valve cylinders." These play back and forward in the valvetubcs. On the upper side of g-i 4, (being the further side in gs. 2 and 3, and the right-hand side in'lig. on thc valve cylinders W, Etc., are two slots marked X XZ, iig. el, near the endof the cylinder, called the valve induction slots, and through the valve-tube lining T, he., at the same side, are two apertures, called the valve-tube induction stets, marked Xx X", XA X, iig. Il. On'the lower side of the vulve tube in iig. 4 are seen, on each side of the block S S, two slots marl-:ed YX Y, Y Y, in the valve-tube lining, called the valve-tube ednction slotsIJ Z ZX, called the i valve inclined planes, figs. and 4, are euch a button or disk ofcircular shape, of Some size as the bore of the volvetubc lining, and chainiered oil', as seen in iig. 3,1m the shape et' an inclined plane. Those inclined planes are connected and firmly (being cast in thc Same piece) with the valve buttons V VX by (each) tiro bars, marked Z Z, Zz Zt, in fig. 4. A* A, iig. 1, and A, iig. 2, are disks (whose section is seen in dashed iines in Eg. 1,) fitting in and firmly fastened (by screwing in or by small screws on the franges) to (peach) an aperture on the sideoii` the valve tube, marked Bx B in fig. l, (defined by dashed lines.) G* C, fig. 1, and C, tig. 2, are short pipes east on the disks Ax Ax, (and generally forming a male screw.) Thess pipes and disk are pierced each with a horizontal hole, (seen in dashed lines in fig. 1,) through which `holes the water comes .in` and goes out.` These i disks AX and AX L, are called the pipc'dislss, and through the right-hand one (in iig. 1) the induction disk, the water comes in, and through the left-handouts (in tig. '1)thc eduction disk," the water goes out. And the operation of my machine is as follows z In gs. 3 and 4 the piston is seen in the middle, and the valves are represented in the same position; the water being thus neither coming .in nor going ont.. The meter being placed onits side, say the side which is at the right hand in figs. 2 and 3, is shaken or bumped heavily. This process shakes the piston and the valves down on that side as far as they will The induction disk and pipe being then (by any convenient method) connected with the hydrantlpipe, the writer is let on. It cornes in, in the direction ot' the arrow on therighthand side in fig. 1, passes through two'slots in left-hand side of chamber Bx, fig. 1, (which slots 4are opposite to and incontinuation of the two valve-tube induction slots Xxz X, lig. 4. vHere, the right eduction slots Y Y, iig. 4, being closed, (by the samc'arrangcment of position of tlieo'alv'os which opens the valve-tube induction slotson that sideof the block S S, the left induction slots XX XX being closed, and the left' cduction slots YX YX being open,) the water passing-.through thc valve-tubc intluction slots Xx Z Xx and lling the valve tube on that side (of the block S S) proceeds upward .and presses on the right-hand side, (see lig. 3,) of the piston. The piston, yielding, moves to the loft, the right-hand end of the slot P, iig. 3, pressing against the clock pin Q, and moving it to the left, (the recession of the piston moving the clock pin back agaim) thus actuating gearing of pawl and ratchet-wheel connected with cog-wheels and dial-plate to register the discharge of water. lThis gearing and clock-werk being in no way different from that in common use, it has not been thought necessary to represent it. The piston having reached its extreme position on the left, and the lel`t-hand hammer horn having passed under the left hammer roller, the left latch knob O'l strikes against the lower part of the left latch and withdraws the top part of the latch from its notch in the side of the left hammer F. The left spring I I, then expanding drives the hammer down with force, and the inclined plane at the bottom of the hammer coming in Contact with the left inclined plane Z, iig. 3, ofthe valve, the latter yields and moves back toward the left, carrying with it, by means of the valve shaft U, the right-hand valve. This shifting of the two right and left valves opens the left induction slots, and the right eduction slots, before closed, and also closes the left eduction and right induction slots, previously open, The water, then, ceasing to como in at the right-hand side of the piston, enters at the left-hand side, and, going up, presses the piston toward the right sido. The right eduction slots being open, the water on that side of the piston is pressed out through them, and passing on to the chamber BX, (see lig. 1,) is ejected in the direction Vof ,the arrow seen on that side. As theipistcn moves from the extreme left to the right-hand side, the inclined plane of the hammer horn O, on that side, liftsfby means of the roller G, the hammer on that side to its position, and the top of the latch L, snapping into its notch retains it there. The .pioon going to the right, the same process just described, of pressing the latch kuch GW on'that side, on the bottom of the latch LX, causes the hammer FX to strike upon the valve inclined plane ZX, when the valves are again shifted, and the water coming in, as first described, the piston proceedsv back again, the hammer horn O, resetting the hammer IW, (as its mate did on the opposite side,)and thustl1e action continues as long as the water runs. The dial above (not shown, but above advertcd to,) announces, on consultation, how much water has been discharged. And I usually arm the hammer inclined planes and the valve inclined planes with steel. And I usually set in a piece of steelin the side oi` the hammers to contain the notch into which the tops of the latter go.- And I prefer to make the latches and also the hammer rollers either of steel or oi' bell-metal. vI laon'ietixnes connect to the piston a horizontalvshaft, like a piston-rod, passing through the cylinder-head on the side on which vthe piston-rod is fixed, and use the same as a motor, propelled by water power. For this purpose I place the latches lower down, and bore a cylindrical hole, horizontally through (or cut a groove, semicircnler in section upon) the upper spring slab E, which slab is then made thicker than is seen in the drawing.

And what I clainlherein as oi' my own invention, and desire to secure by Letters Patent, isl 1, -I-elaim the arrangement in a meter or nioter, ot` two valves, cach one being both for induction and eduction, thc said valves beingconnected together, and acting alternately in separate chambers or valve tubes, when the same are used in reciprocal action with a piston and actuated by percussion, all substantially as and for the purpose described. y

2. I claiui actuating the valves of a meter or et a motor, by the alternate percussion of two hammers upon inclined planes connected with thc valves; the hammer being operated by the motion of a piston, all substantially as and for the purpose described.

3. I claim the arrangement, in combination with the hammers, of the p'awls or latches, with their respectivo springs, to retain the hammers at their highest elevation, when the same are actuated bythe piston, discharging said pawls, all substantially as and for the purpose described,

4. I claim, with a meter or motor, the device of the horns or projecting inclined planes, attached to the pistofn, for the purpose of raising; the hammers, when the saine operate substantially as and for the purpose described.

5. I claim the arrangement in a meter or in a motor, of a piston-containing cylinder, and a valve-containing cylinder, when the valvesare operated by percussion, all substantially as and for the purpose described.

6. I claim the general arrangement and construction of the machine represented, all substantially as and for the purpose described.
